3.5 starsI always love reading stories on time travel because it is interesting how authors choose to explain the phenomenon. And while I really enjoyed the action-packed story which kept me at the edge of my seat, I felt that the science fiction element was a bit lacking. I still don't particularly know how time travel "paradoxes" work, nor do I completely understand how altering the past doesn't completely change the future. However, that wasn't the point of this story, and the author used time travel as a means of illustrating other concepts. If you could go back in time, how would you view yourself? If you could look into the future, how would you feel about who you become? What if "fixing" what is wrong with the now involved going back to kill the one person you loved? Could you do it?
